COMBINED SEED GRADlER, CLEANER, AND PURIFIER.

Specification of Letters Patent. Patented July 26, 1910,

Application filed July 20,1909. Serial No. 508,582

To all whom "Lt-may concern:

Be it known that I, CnAnLns B. Basso),

residing at 'lippecanoe City, in the countv" of Miami and State of Ohio, have n-iventcd a new and Improved Combined Seed Grader, Cleaner, and Purifier. of whicu the following is a specification. I

This invention relates to that type of machinesthat clean, purify and separate and grade the grain as it. is carried therethiiough, and it has for its object to provide a machine of this type, that comprehends, generally, an improved construction and ar-ange1nent of the upper shoe ard the blast devices wln reby the 'air can be readily directed to b ow upwardlyfor blowing the light chaff and foul seeds back through the rear-end of the machine and through the top shoe, or directed downwardly for blowing off the chaff and out through the back ofthe machine and nnfoul'seeds that est-ape from the top shoe and der the top shoe.

In its more conplete nature, my invention embodies an improved arrangement of the .top shoe, and means for imparting oblique motion thereto whereby to throw the coarse chaff over the rear of the machine to discharge onto the floor.

In its still more, complete na Lure, my invention includes an improved .COllE-illlltjiilOll of upper and lower shoes, the 11' cans for susp'endingthem within the main fran'ic,-and a special construction of actuating devices for imparting the desired motions to the said shoes,- iny said invention, in its subordinate features, consisting. of certain details of construction and peculiar combination of parts all of which.will be hereinafter fully de-.

scribed, specifically pointed out in the ill).-

pended claims and illustratcfl in the accompanying drawings, in which Figure 1, is a perspective view of my improved machine. Fig. 2,- is a vertical, longitudinal section of the sanflc, the blast valve or gate shown set to direct the fan blast below the top shoe; section of a part of the machine, showing the said fan or valve as set to direct the fan blast through the top shoe. Fig. 4, is an end elevation of my improved machine. Fig. 5. is a transverse srction on the line 5-5 on Fig. 2, looking ii the direction'of the'arrow. Fig, (1, is a Ptl'Sl'lQCllYQ view of the screens of the middle shoe. Fig. 7, is a similar view of the bottom shoe.

In ,the pract ical threaded as at all to receive "understood from Fig. 3,. is a detail 't' onstruction, my machine has opposite side frames, each built up of four legs or uprights 1-it that-are firmly braced by the horizontal beams 2 2 in a manner clearly understood from Fig. l, by reference to which it will be noticed that a hopper 3 is motmtcd between the upper ends of the members 1 and is bolted or otherwise made'fast. thereto as-shown in the drawings, although it maybe adjustably supported so it may be raised. or lowered, as desired.

4 designates a regulating slidc mounted at the discharging throatof the hopper for controlling the grain outflow therefrom, the said slide being mounted at the ends in suitableguides on the hopper f'ame, andi-s provided with a pendentbracket lO-that the threaded shank 42 of a crank rod 43, as clearlyshown by Figs. 1 and 2. 1

5 designates theshorttop shoe that comprises the end frame members otl iit), a cross piece 51 at. the lower end that forms a. check against the discharge of the grain over the lower end of the coarse screen 52 mounted over a solid sheet metal bottom plate which in connection with another similar plate ailbelow it and also mounted on the frame members 50, forms an air chamber a, presently again referred to.

The top shoe 5 is supported at the inner or lower end, on the c 'ank strap irons l3t' the upper ends of which-pivotally connect with brackets 56 on the sides of the shoe and whose lower ends have a series of apertures 1 for adjustablv receiving the cross rod 7- that supports the outer or lower end of the middle shoe 8, the said irons 6 also having a number of apertures 62 about'midway the long portions thereof for adjustably receiving pivot pins 9 that engage the bracket irons 90 secured to the cross timbers 2 of the framing as will be clearly Fig. 1, by reference. to which it will be also noticed the upper end of the shoe 5 is detachably. supported on a cross rod 1.0 held in the lower ends of short strap iron links 1111, the upper ends of which are .pivotally hung in brackets 12 -12 on the sides of the hopper frame, andto provide forvertical adjustment'of the rear end of the shoe 5 the same has notched p1ates-13--13 to receive the rod 10, as shown.

14 designates a substantially inverted I- sha'ped'bottom or partition located under the top shoe 5 .andwhose inner end extends under tndinal partition, providing, as it were, a duplex set ofsc'reens of difiierent' mesh, a final cleaning and separation. of the already cleaned and graded material. is obtained.

Having thus described my inven ti on, what I claim and txesire to secure by Letters Pair-int, is:

It. in a machine of the class described, the combination with an. upper shoe having a plurality of superposed screens and a separate. discharge "or each screen at the. delivery end thereo't'; oi? a lower shoe, said lower shoe including two separate and independent longitudinal screening surfaces mounted side by side, said screening surfaces being of difierent mesh and held to receive the graded discharges from the upper sh0e, and having a separate discharge for each. of the said surfaces, and means at the receiving end of the said lower shoe for deflecting the sticks and trash, as set forth.

In a machine of the class described, the cm'libin ion with an upper shoe having a plurality of superposed screens and a separate discharge at end thereof; of a lower shoe having two distinct longitudinal screening surfaces of dif-,

t t t i or each screen at the delivery\ ferent mesh that receive the graded discharges from the upper shoe, said two screening surfacesbeing mounted side by side, and havinga separate discharge for each of the said surfaces, and bridge members at the receiving end of each of the screening surfaces for deflecting the trash, stic 3, etc.

3. In a machine of the class described, the combination with an upper shoe having a pluralityof superposed screens and a separate discharge for each screen at the delivery end thereof; of a lower shoe having two distinct. longitudinal screening surfaces of different mesh that receive the graded discharges from the upper shoe, said screening surfaces being mounted side by side, and having a separate discharge for each of the said surfaces, and bridge members-at the receiving end of the said screening surfaces for deflecting the trash and sticks and flexible members secured to the bridge members and loosely sustained upon the said screen ing surfaces.
